Build 1: Auras, Beams (all 4 DU) and all minions excpet one mage which you build 2nd build phase. (The Beam of the east side should reach all crystals) I recommend 3k Range on monk. 

Combat 1: Hint 1; Usually where i start Combat 1 to get a full mana bar to upgrade the beam on the east side. I try to max it on the first combat phase and then i go to hint 2, farm and spam drop mana for the 2nd build phase.

Build 2: Build the mage-minion before or after towers, whatever fits your preference. Hint 3: I build the DST's on the top left (They are for stuck djinns/spiders + the slow wyverns) and you don't need to stack them. And then i go to Hint 4: and STACK DST's + one LT. (Make sure they are a bit further south than the wooden guy standing there. It's to avoid any stuck ogres and etc) this is also where you will be placing your Boosting summoner(s) and your TBoost monk when you're done upgrade Beams, auras and towers. 

Upgrading: Beams to max, Auras to 1 star (Max if you want) and all towers to max lvl. 
After finishing upgrading you bring all your characters in (Tboost, Boosting summoner(s) + Apprentice. I use Huntress + Apprentice guardian. 

Minions: The south archer squad is standing at the bottom of the stairs and mage + spider at the top of it. 

Stats: Im rocking 6-7k on main stat on my builders, but you should be able to do it with a lot less. 

Failing? I got some tips if you are failing. You can remove one of the DST's pointing southwest and put gas traps on hint 5 if your stats are knd of low. 
Also you need to make sure to tbboost for as long as possible during boss round if you can't kill all the bosses fast enough. Otherwise go protect east crystal from hint 5 once again to make sure golden orcs doesn't sneak by. 

Hope you have fun and enjoy the build. GL&HF <3 Paan :)
